SPECIFICATION forming part of Letters Patent No. 569,389, dated October13, 1896.

Application filed January 27, 1896. Serial Nol 576,973. (No model.)

To @ZZ whom, it may concern:

Be it known that I, JAMES B. SCHUMAN, a citizen of the United States,residing' at Columbia City, inthe county of lVhitley and State ofIndiana, have invented certain new and useful Improvements in GrainRecleaners and Separators; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to that class of recleaners and separators whichare designed to perform their functions automatically and continuouslywith the act of elevating and conveying grain from a thresher andseparator to a point where it is delivered to a bag ger or weigher; andit consists of a new and novel arrangement and combination of certaindevices in connection with the delivery end of a pneumaticconveyer-pipe, as will be more fully described hereinafter.

My object is to provide a device for this purpose which shall beapplicable to all convey ers in which air is used to force grain througha conveyer-pipe, providing means for simultaneously recleaning thegrain, separating it from the minute particles and from the airblast,and delivering it to any receptacle or a weigher or bagger; and withthese objects in view my invention is simple of design, easily andcheaply constructed, and is durable, efcient, and economical in use.

Referring to the drawings, Figure l represents myinvention connected toan elevatingconveyer which is attached to a separator in connection witha fan-blower. Fig. 2 is a side view, on an enlarged scale, showing theinternal arrangements dotted in. Fig. 3 is a perspective view of the endand under side, and Fig. 4 is a cross-section on the line X X of Fig. 2.Fig. 5 is a central sectional view of the device.

In the drawings, H is a fan delivering air through the pipe G,discharging into the conveyer E, into which grain flows through thefunnel F, the air approaching from behind the grain as it enters theconveyer, forcing it out through the conveyer and into the recleaner andseparator A, which in some cases has a tapering inlet D, while in othersthe connection is direct with the straight portion of the convcyer-pipe.

a is a cone having the apex. central with the center of the chamber ofthe recleaner and inlet pipe to saine. For a short distance above thebase of the cone the sides are perpendicular to the base. The cone issuspended and secured near the outer end of the recleaner to collar f bymeans of brackets e. Both ends of the recleaner are otherwise inclosed,except at the inlet and outlet. At the upper end a circular opening isprovided, into which is inserted and secured a tapering collar f,terminating at the lower end in a sleeve or collar having parallelsides, which extends inward to near the base of the cone, but issomewhat smaller than the cone in diameter, so that a passage for theoutlet of the chaff is provided between the cone and the sleeve at b,the refuse, together with some of the blast, passing around the coneacross its base and outward through the interior of the sleeve,discharging from the opening I, the inclosed end around the sleevepreventing the grain from passing out with the dust.

To prevent any lodgment of small grain or dust in the interior of thecone, a small opening c, having a protecting-lip d, is provided at thelower side of the cone near the apex.

B is a tube connecting with the body of the device, providing freedischarge of the air.

C is a discharge-pipe through which the grain falls by gravity to aweigher or bagger, or elsewhere, as maybe desired. The upper portion ofthe body is provided with a screen J of iine mesh, and likewise at J atthe upper side of the end face. This allows a portion of the air to passthrough the screen and assists in carrying the grain upward, and moreeffectually tumbles it around the interior to thoroughly reclean it.

Having described my invention, what I claim, and desire to secure byLetters Patent of the United States, is-` l. A recleaner and separator,in combination with a pneumatic grain-conveyer, comf IOO of the line ofthe air-blast from the eonveyerpipe; a grain-discharge opening at thelower side of the main chamber at or near the said inlet; a sleevedepending from the upper end of the main chamber so attached to thedustoutlet end that all portions around the said sleeve are inolosed atthe lower side of body and end7 While the upper portion of the body sideand end is provided with a screen of elose mesh a cone secured anddepending from the inner side of said main Chamber, said cone be ingslightly larger at its base than the dialneter of said sleeve andoverlapping the same but slightly separating it to provide a passagebetween lower end of said sleeve and base of said Cone, said @one havingat the lower side of its apex a perforation partially Covered by a lipso that a blast from the inlet will strike the point of the Cone and bedeiieoted from said lip and from entering said perforation,substantially as and for the purposes shown and described.

2. The combination, with a grain-oonveyer of the kind described, of areoleaner and separator attached to the discharging end of saidconveyer, comprising the main 'body portion having the central inlet;the air-outlet at the upper side; the grain-outlet at the lower side;and the eene supported Within said body portion, the apex of said @onebeing oentralwith said inlet and situated in line therewith; the

sleeve having the annular flange, which incloses the outer portion ofthe end of said body portion opposite the said inlet thereto, saidsleeve being somewhat smaller at its inner end than the base of saidcone, the said @one and said sleeve providing, as situated, a defleetorand an outlet-passage for dust or ohait, substantially as shown anddescribed.

In a pneumatic grain-oonveyer oi the kind deseribed, the Combination ofthe reoleaner A composed of the' cylindrical body portion having theinlet D; the airoutlet B;

the grainputlet C; the @one a, having the opening c and lip CZ; thesleeve f having the annular flange covering the end of said body portionaround said sleeve7 said cone being supported in front of said sleeve soas to provide a passage b between, said sleeve being open to theatmosphere at I; the screen J at upper portion of said body portion, andthe screen J around upper portion of the discharging end of said bodyportion, substantially as and for the purposes shown and described.

In testimony whereof l aiiix my signature in presence of two witnesses.
